IMPROVED SNAP-HOOK 'ilgt rlgitul'e riferirsi: tu iml than trttcts rient tnt making putt nf 1 e tranniel TO ALL WHOM IT 'MAY GONCERN:

Be it known that I, J. C. Covsnr, of Newarlt,'in the county of Essex, and in.. the-Stute of New Jersey, lieve invented new and useful Improvements in Snap-Hooks; and do hereby declare that the following'is n full,

clear, and exact description thereof, reference being had topthe accompanying drewiws, :tndvto the lettersof reference marked thereon. l

In theonnexed drawings meking part oilthis specification, A represents the shnnkoi` a snap-hook, which iscust with a. square'groove in it freni .near one end to that peint n'enr, the other endwhere the hook B commences; I, represents a bridge cest across this groove; D represents o. sliding bolt, which isenst o portionof its length to t snugly ,within vthegroove in the shank and e represents n'eoiled wire spring',`\ vhich Ais placed in' 4 the grohve behind the bolt D, pressing at one .end against seid` bolt, and nt the other against the metal of the v shank at`the rearend ofthe groove. The-bolt D is provided with u. pin, a, by ineens of which it is ioreeddmek,

at the same time compressing the spring. Fitted upon the shank Aand over thejgr'oove in it, is n p lnte,

The forward end of this plate is beveiied und fitted in a- V-shaped grooveint one side of the' bridge I, while the roerend of said plate-is secured to the shank by n screw. VThis plete eifectunlly ciosesup the g'roovei'n the shank, except et that end through which the 'bolt protrudesL-und securely'proteovtszthe spring andboltwithin the grove from dirt or dust or'ice, die., and also from injury by'mashing or striking, tlmsennbling them nt nll times 'and under all circumstances to work freely and easily. The {Jina works through n groove, d,.in. the plate.

The forward end ot'- the bolt is pressed by the 'spring c firmly against the end fof the hook B, both thebolt und hook being runde Vsquare on .their ends, so-that they will t snngly together. There-nd of the shank opposite the hook is mode rounding, os seen, and, with of shoulder at s: w, und is `provided with 's suitable holle; through which a pin may pass, for pivoting it between thejaws ofthe hold-back, with Awhich it is' intended vto be used.

I use. two of these snep-hooks, one at eaehend of the hold-back, for hooking into the heme at" each side. p

This snep-hook is not made with e loop 'as others are, to be strapped to theerticfie with' which'theyere to be used, and then, by casting it in" the manner described, and providing it with n plateto cover up the bolt and spring, I make a. snap-hook Whichrn'ill work freely in all kinds of weather, and without danger of having Aits v parte broken or dishrzanged. i y u By casting,r the bolt D in the manner shown, it een be dropped into its groove in'the'shu-nk, in front of the simple spring e, without any finishing, and ithus simplifies and makes the cost of the hook much less than it would he were a pi formed on it to run through the spring. l

By the use ofthe plate, the spring is kept in place without n. pin running through it.

Having thus fully'described tny invention, whet I cla-im ars new, and desire to secure'by-Let.ters Patent, is

As en article of manufacture, providing the' shnnk'ef the snop-hook with o. groove, into which `is dropped the siidng-holt D'and loose spring e, snid groeve being covered by menus ofthe plete G, and the bridge L'which conceal, keep in place, and'protect the spring .n.nd bolt, one end of the shnnk being so formed that it een be pivotcd to a hold-back, the several parte being constructed and arranged as und for the purpose set forth.

In testimony that I claim the foregoing, I have hereunto set my hand, this 6th dnyl'of February, 1868.
